Definitions

  • the invention relates to a transport system and a transport method.
  • Machining devices can be designed to carry out a variety of machining operations, such as cutting or separating operations, on continuously fed workpieces.
  • the workpieces to be machined can be transported through the machining region of a machining device using one or more transport means. Machining devices in which the workpieces continuously pass through one or more machining regions are also referred to as through-feed machines.
  • a transport system which can be used to transport the workpieces to be machined through the machining region of a through-feed machine is disclosed in EP 2377786 A1, for example.
  • a transport system may comprise transport structures which are in direct contact with the workpiece to be machined during the transport thereof, such as chains, belts or other circulating transport means.
  • the connection between the (circulating) transport means and the workpiece, which is necessary for transporting the workpieces, may for example be established by the static friction, resulting from the force of gravity, between the workpiece and the transport structure or by driver elements.
  • Top pressure belts may additionally be used.
  • Inside a machining device such a transport system is usually arranged in a transport means housing.
  • the functionality, reliability and service life of a transport system with circulating transport means depends on several factors, such as the appropriate preload, the positional accuracy of the gearing and the degree of wear of the circulating transport means. These parameters change during operation on account of mechanical and thermal stress. This can result in reduced precision of the conveying operation, which in machining devices can be reflected in reduced machining quality and machining accuracy.
  • transport systems require maintenance after a certain period of time in order to readjust or amend the parameters that have changed depending on the degree of wear. Without timely maintenance and adjustments, the transport system may exhibit premature wear or may even break down. This can cause significant economic damage.
  • One known solution is to carry out maintenance in a short maintenance cycle such as every two weeks. However, this preventative measure has economic disadvantages owing to the reduced availability of devices.
  • the object of the invention is to provide a transport system and a transport method which have a precise conveying operation, a high degree of reliability, a long service life and low maintenance requirements.
  • the transport system comprises at least one sensor for detecting at least one condition variable, in particular the preload force and/or instantaneous load on the at least one circulating transport means and/or the dynamic behavior of at least one section of the transport system, and at least one actuator for influencing at least one condition variable of the transport system.
  • At least one sensor for detecting at least one condition variable allows the conveying operation of the transport system according to the invention to be continuously monitored, so that any problems, and optionally also the causes thereof, can be identified early on. Based on this, the system can be actively influenced in order to eliminate or at least mitigate the problems and, where possible, also the causes thereof.
  • Vibration and noise emissions can be minimized by virtue of the optimized preload forces of the chain.
  • the transport system offers improved process reliability as a result of detecting incorrect process parameters.
  • a reduction in maintenance costs and a considerable improvement in service life and availability of devices can be achieved.
  • wear and special events such as short-term force and voltage peaks can also be detected by the at least one sensor, and the transport system can in this case be stopped automatically.
  • Preventative maintenance based on measurement data and statistical models can also be facilitated.
  • the service life of the tool and the machining quality and machining accuracy of a workpiece to be machined are improved with machining devices equipped with a transport system as according to the invention.
  • the transport system comprises a plurality of circulating transport means such as in the case of so-called double-sided devices. Thanks to the invention, a particularly synchronous operation of the circulating transport means can be achieved, and therefore the aforementioned advantages can be achieved in a particularly pronounced manner.
  • the guide arrangement to comprise at least two sections, wherein preferably at least one actuator is provided between a first section and a second section of the guide arrangement.
  • the transport system to have at least one second sensor for detecting the dynamic behavior of at least one section of the transport system, in particular the circulating transport means and/or the guide arrangement.
  • at least one sensor it is particularly preferred for at least one sensor to be arranged on at least one circulating transport means in order to detect the vibration behavior of the circulating transport means as soon as possible and in an undistorted manner.
  • at least one sensor it may also be advantageous, however, for at least one sensor to be arranged on the guide arrangement.
  • At least one actuator comprises an actuating element which is capable of controlling or adjusting at least one condition variable of the transport system ( 1 ) by the application of force or by way of positional adjustment and which is preferably selected from a pneumatic actuator, a hydraulic actuator, an electromagnetic actuator, a piezo actuator, a threaded spindle, a servomotor and a linear motor.
  • actuating element as an “active” actuator allows in particular the dynamic properties of the transport system to be optimized in a particularly effective manner, wherein the data detected by the at least one sensor can be used again here. In this way, an active transport system is obtained which can adjust its properties to a wide variety of influencing variables and parameters such as the conveying speed, conveying load, temperature, state of wear, degree of soiling etc.
  • At least one actuator to comprise an adjustable damping element, the damping properties of which are variable, in particular controllable or adjustable.
  • the at least one adjustable damping element fulfills a dual function, in that it continuously facilitates vibration damping of the transport system, yet this damping behavior can be actively adjusted in a controlled manner, such that overall the result is an optimal behavior of the transport system that can continuously be adjusted to requirements and operating parameters.
  • the transport system comprises a control module which is configured to control, preferably adjust, the at least one actuator and/or at least one driving means for driving the circulating transport means depending on a detection result of at least one sensor.
  • the invention provides an active transport system, as already mentioned above, which can adjust quickly and effectively to the respective requirements and operating parameters. This contributes significantly to achieving the underlying object, namely to providing a transport system having a precise conveying operation, a high degree of reliability, a long service life and low maintenance requirements.
  • the control module is configured to control or adjust the at least one actuator at least occasionally at a frequency of at least 1 Hz.
  • This allows the concept of an active transport system to be implemented particularly consistently, and there are no time periods in which vibrations can increase, damage can proliferate or machining inaccuracies can add up. Once again, this contributes to achieving the underlying object set out above.
  • the at least one actuator to be controlled not only in a resting state of the transport system but rather for the control module to be configured to control or adjust the at least one actuator during a transport movement of the at least one circulating transport means. It is therefore not necessary to stop the device for the purpose of controlling the at least one actuator. Rather, according to this development it is possible to always respond in a flexible manner to the respective operating parameters even during the conveying operation of a certain workpiece.
  • the at least one actuating element can, for example, be controlled as soon as a workpiece conveyed on the transport system engages with a machining assembly, such that even vibrations and forces exerted on a workpiece and therefore on the transport system by a machining assembly can be balanced out by the transport system according to the invention.
  • a drastic improvement of machining accuracy and machining quality can be achieved in this way, while at the same time damage to the transport system and also to any machining assemblies present is avoided.
  • the transport system according to the invention may also be a passive transport system in which the items to be transported are advanced in a different way
  • the transporting operation of the transport system can be influenced to an even greater degree, for example by the driving means being controlled or adjusted on the basis of a detection result of the at least one sensor.
  • the circulating transport means can be designed in a variety of ways.
  • articulate transport means such as, in particular, a transporting chain and/or a belt.
  • Such circulating transport means have proven successful in practice.
  • the advantages of the invention can be realized particularly effectively with such circulating transport means.
  • the so-called polygon effect can be compensated for by the invention, such that as a result a robust and precise transport system having a high degree of reliability and a long service life as well as low maintenance requirements can be provided with simple means.
  • Similar considerations apply to belts with which a polygon effect can also occur depending on the design thereof, and with which dynamic peculiarities can occur depending on the longitudinal rigidity thereof, which can be advantageously compensated for by the transport system according to the invention.
  • the transport system to comprise an interface which communicates with the control module and which is designed to send at least one condition variable of the transport system to a database and/or to receive data from a database in order to relay this to the control module.
  • the database may be provided locally and may be networked with a transport system, for example, or optionally with a plurality of devices.
  • the advantages set out above can be achieved in a particularly comprehensive manner.
  • the transport system to comprise a display device which is designed to visualize data, in particular from the at least one sensor and/or actuating element.
  • the data may be raw data and/or processed data.
  • a transport method according to the invention using the transport system according to the invention is disclosed herein. This is characterized in that the detection of at least one condition variable takes place during the actual transporting process. It is therefore not necessary to stop the device or to carry out a special calibration operation. Furthermore, the method allows direct feedback, i.e. controlling or adjusting is carried out continuously during the transporting operation, which facilitates the advantages set out above.

  • the transport device 1 can also be used as a stand-alone machine, or that the transport system 1 can also be combined with completely different devices.
  • the transport system 1 has a circulating transport means 15 which in the present embodiment is formed by a transport chain. Alternatively or additionally thereto, however, other circulating transport means such as belts or the like can also be used.

  • the guide arrangement is formed of a plurality of parts. As can be seen in FIG. 2 , for example, the guide arrangement may comprise a first section 6 and a second section 8 .
  • the transport system has a plurality of sensors 10 , 11 and 12 , which are used to detect various condition variables of the transport system.
  • a first sensor 11 is arranged on the first section 6 of the guiding means 4 and is used to detect a preload force or instantaneous load on the circulating transport means 15 .
  • a second sensor 12 is arranged on the second section 8 of the guide arrangement and is used to detect the vibration behavior or dynamic behavior of the second section 8 of the guide arrangement as well as indirectly also of the circulating transport means 15 .
  • a further sensor 10 is provided directly on or in the circulating transport means 15 and thus directly detects the vibration behavior of the circulating transport means 15 .
  • the transport system comprises a drive 14 for driving the circulating transport means 15 .
  • the transport system 1 has an actuating element 13 which in the present embodiment is arranged between the first section 6 and the second section 8 of the guide arrangement, wherein, as shown in FIG. 2 , the first sensor 11 is still inserted between the actuating element 13 and the first section 6 of the guide arrangement 4 .
  • the actuating element 13 is used to influence one or more condition variable(s) of the transport system, for example by changing the clearance between the first section 6 and the second section 8 of the guide arrangement 4 and thus directly impacting the preload force or instantaneous load on the circulating transport means 15 .
  • the actuator 13 is designed as an actuating element, wherein this may be, for example, a pneumatic actuator, a hydraulic actuator, a piezo actuator, a threaded spindle, a servomotor or a linear motor. Combinations of these actuators and other actuators are of course also possible.
  • the controller 30 operates at a frequency of 10 Hz, although other frequencies are also possible, for example in the range of at least 1 Hz to 100 Hz or more.

  • the database 40 is stored “in the cloud”, i.e. the interface 32 communicates with the database 40 via the internet or another suitable remote data transmission link.
  • connection of the controller 30 to a database facilitates on the one hand the targeted data collection and networking of whole production systems or even independent devices at a wide variety of locations.
